illegitimate fuel consumption
 
Hello,

i install the MPGuino yesterday. It seems that all worked, but...
When i acellerate the fuelconsumption doesnt increased:confused:
The consuption raised only in lower gears..

What i do wrong?

What is your fuel injector input wire connected to?

Jack-Lee 07-02-2013 05:10 PM

I tested both: The + and - Wire to the injector
+wire : nothing to see on the display
-wire : works, but not correct.
When i accelerate, the value is not change at all.
I think the injector is a "Peak and Hold" type.. ?

It may be possible. Can you tell me what the coil resistance is, of your fuel injector?

Hello,

the resistence : 1.3Ohm
Its a Singleinjector

The Injectors from the stronger MPI Motor : 15,9Ohm

This injector is very likely a peak-and-hold injector. They have not yet figured out how to get an MPGuino to work with these, I'm afraid.

That injector is very likely a normal injector.

Hello,

good.. i had two MPGuino. One from MTH and one vom "Wiseman".
The Guino from Wiseman should work with this "peak and hold" Injectors!
Fine :)

Your setup works just fine. You do'nt need to select injector type.
Adjust the "Injector delay" in the menu. Try adjusting it up or down until the instant consumption is realistic.

If your inj delay is too big, then it loses data (=accelerations), and if too small, it goes nuts.

And every up-to-date MPGuino supports P&H injectors as far as i know.

Hi,

the consumption dont change when i accelerate...
And it is a peak and hold injector :D
I try it with the MPGuino from Wiseman (he has impliment the software solution from the Guino-Wiki)

You sure about that? The MPGuino wiki still has an advisory that states that peak-and-hold injectors are not yet supported.
